Daventry District Council will tonight vote on whether to back the proposals to create two new unitary authorities in Northamptonshire.
If approved, the council will be agreeing to end the existence of the district council and the six other district and borough councils across the county, as well as the cash-strapped county council.
They would be replaced in 2020 by two unitary authorities with Daventry adjoining Northampton and South Northamptonshire, and Kettering, Corby, Wellingborough and East Northamptonshire making up the other.
So far the county council, Northampton Borough Council, the Borough Council of Wellingborough, East Northamptonshire and Kettering have all backed the proposal, meaning they will definitely be submitted to the Government for approval, regardless of the outcome of tonight's meeting.
South Northamptonshire and Corby will also vote tonight.
The unitary proposals are the only item on the meeting's agenda, which starts at 6.15pm.
